Bicycle Seat Post for Teledyne

Bought this 26.8 mm diameter seat post (the most common size is 27.2 mm, which I have a couple of but the Teledyne uses 26.8 mm).

The seat post is too long.  The frame is too big for me so the seat post only needs to stick out a couple of inches from the seat tube.  With about 4 inches of overlap needed, about six inches from the bottom of this post can be cut off.  I used a metal cutting chop saw to shorten in.

The seat post does not slide down the seat tube smoothly.  It's quite a tight fit and wants to bind.  I'll have to take a little bit off the outside of the seat post so that it's not so tight.
Cut off about five inches from the bottom.

The seat post has fairly large machining ridges on it.  If I sand down the ridges, it should be just the right size for the seat tube.
